Definitions

  • the invention relates to an installation for recovering food-grade blood in a slaughterhouse; by "food grade blood” or by the abbreviation “edible blood” is meant blood from healthy animals and having qualities of sterility and hygienic cleanliness making its components capable of being used as additives in the most demanding applications, in particular, as additives incorporated into a food product intended for animals or humans (it is understood that the term “food quality” qualifies blood as such and has no limiting character as regards possible applications of it).
  • blood is a rich product, which contains in particular a noble protein (globin) of a nature to enrich in an extremely interesting way many food products for humans or animals) or capable of 'be used in other applications because of its interesting technological properties (foaming and emulsifying power).
  • a noble protein globin
  • the invention proposes to provide an installation making it possible to recover the blood produced in slaughterhouses and to store its components (in particular cruor and plasma), under conditions compatible with subsequent use as food additives or with any other application requiring analogous qualities called nutritional quality
  • Another objective of the invention is to considerably reduce the quantities of rendering blood flowing into slaughterhouses by the collection means provided for this purpose.
  • the counting means comprise a pulse counter, called the entry counter, located at the entrance to the bleed passage, and a pulse counter called the exit counter, located downstream of the circuit. butchering at the veterinary checkpoint.
  • Each primary tank has a capacity for storing blood from a predetermined number (N) of animals, and the number of tanks is adapted to allow temporary storage of a quantity of blood greater than that which would be provided by the number maximum number of animals likely to be present at any given time on the chain (from the entrance to the bleeding corridor to the veterinary checkpoint).
  • the control unit which can be a programmable automaton is adapted to control (in the absence of intervention from the veterinarian) the progress of the following normal cycle: referral of blood to another primary tank at the end of each batch of N animals registered by the entry counter, and emptying towards the alimentary blood circuit of the tank containing the blood of the last batch of N animals registered at the exit counter.
  • this unit controls the stopping of the trans carrier in the bleeding corridor and selects the primary tank which contained the blood of the consigned animal as well as possibly the following tanks. This or these tanks are then emptied towards the rendering blood collection means in order to avoid pollution of the food blood already collected.
  • the blood of a given beast is not. never transferred to the food blood circuit before the time when it passes to veterinary control thanks to the provisional storage provided in the primary tanks: the installation in accordance with the invention thus makes it possible in all cases to avoid polluting food blood already transferred by the blood of a sick beast.
  • the receiving chute, the conduits and the primary tank (s) which have been in contact with the polluted blood are subject to cleaning by means of cleaning liquids which are evacuated to the sewer.
  • the receiving chute allows the blood to be collected at the same time that it springs from the animal under appropriate conditions of cleanliness and sterility.
  • this chute is preferably associated with ventilation and filtration means, adapted to maintain the interior thereof in slight overpressure in sterilized air.
  • this chute is also associated with means for injecting one or more additives into the collected blood, in particular anti-coagulant and / or preservative products. This avoids any alteration or coagulation of the blood in the installation, and its components (cruor and plasma) can be obtained and stored without denaturation or disappearance of their food quality.
  • said chute is made with inclined guide cheeks situated on either side of the slot of collection, so as to guide the beast in the vicinity of the bled part thereof: the blood gushing from this part penetrates directly through the slit of re harvest without external contact and to the exclusion of all other bodies.
  • the shape and the inclination of these guide cheeks are adapted to the physical characteristics of the animals to be bled; As will be seen below, two types of troughs can be provided, one for the recovery of the blood of calves or animals with anal physical characteristics - large gues, the other for the recovery of the blood of large bovines or d animals with similar physical characteristics.
  • the installation according to the invention can combine means specifically adapted to calves, equipping one or more working chains of the slaughterhouse and means specifically adapted to large cattle, equipping one or more other chains.
  • the installation shown by way of example in FIG. 1 comprises specific means for recovering the blood of food-grade calves, specific means for recovering the blood of large bovine animals of the same quality and common means for storing cruor and plasma from this blood of calves or oxen; this facility is called upon to equip a traditional type slaughterhouse with (at least) two production lines, consisting of each with a slaughterhouse, a bleeding corridor, a butchering circuit and channels for collecting rendering blood.
  • the part of the installation intended for the collection of blood from bled animals comprises a blood receiving chute 1 or 33 arranged in each bleeding lane.
  • the chute 1 that can be seen in Figures 2 and 3 is intended for calves and comprises, on its upper face, two cheeks la and lb inclined in the same direction and situated on either side of a collection slot lc .
  • the cheek is inclined at about 45 ° for guiding the calf of the muzzle as shown in fi g ures, while the cheek lb has an upper portion having a similar inclination and a lower part of greater inclination ; this cheek 1b thus ensures the guidance of the calf's head at the sound level: the calf's head is slightly inclined as shown in Figures 2 and 3 which allows direct flow of blood through the slit lc.
  • the chute 1 is supported by supports 2 above the bottom of the corridor which is conventionally provided with a grating surmounting a channel (made by a concrete form) for the collection of rendering blood.
  • the chute 1 extends over the length of the bleeding corridor (which can be of the order of 3 meters) and its bottom ld is inclined towards one end to allow the flow of blood; in the example, this inclination is directed upstream, that is to say towards the entrance to the corridor where the calves arrive.
  • the chute 1 comprises a ramp 3 for spraying an additive in liquid form, such as an anticoagulant and preservative additive.
  • an additive in liquid form such as an anticoagulant and preservative additive.
  • This ramp 3 which extends over the entire length of said chute makes it possible to intimately mix this additive with the blood, practically at the instant when it springs from the animal.
  • the bleeding corridor is equipped, above the chute 1 and on either side thereof, with plates 4 and 5 of posi calving, which extend along the corridor and are arranged as shown in Figure 2 so as to maintain the body of the calf in a slightly offset position relative to the vertical, front legs directed towards the rear.
  • the plate 5 is slightly further apart from the chute than the other plate 4 and descends lower than the latter.
  • the calf attached by one or more rear legs to a conveyor hook 6 which allows it to be moved slowly along a rail in the bleeding corridor, has approximately the position shown in FIG. 2.
  • the speed of progression can be of the order of 1 meter per minute.
  • a pulse counter symbolized at 12 in Figure 1
  • this classic counter in itself can be electromechanical (rod pushed back by the calves) or optical.
  • Another counter symbolized in 13 is placed at the outlet of the chain downstream from the butchering circuit, at a veterinary control post where the animals are examined.
  • the chute 1 is associated with a fan 7 equipped with filtering means and air sterilization means (for example / or sterile laminar flow / battery of ultra-violet lamps, which allow send clean and sterile air into said chute, putting it in slight internal overpressure.
  • filtering means and air sterilization means for example / or sterile laminar flow / battery of ultra-violet lamps, which allow send clean and sterile air into said chute, putting it in slight internal overpressure.
  • the spray bar 3 is connected to an additive injection assembly 8, composed of a reservoir and a metering pump making it possible to adjust the flow of additive delivered to said boom.
  • the receiving chute 1 is connected to primary tanks such as 9, by means of blood flow switching means constituted in the example by a series of valves, 3 ways, 2 directions such as 10 ; a drain valve 11 is provided at the end of line to allow washing.
  • these primary tanks can be 4 in number and each have a capacity slightly greater than the volume of blood supplied by 10 animals (70 liters).
  • the bleeding and butchering time of each calf being approximately 20 minutes (duration separating the passage to the entry counter and the passage to the exit counter) and assuming that the average rate of the chain is 60 calves at the hour and its maximum rate of 90 calves per hour (usual performance of a current chain), the maximum number of calves present simultaneously on the chain is 30, so that the primary tanks 9 allow temporary storage guaranteeing that the blood of an animal has not yet been transferred downstream of the installation when this animal passes to the veterinary checkpoint.
  • the primary tanks 9 are connected at their outlet to drainage circuits and referral means which allow either to transfer the food-grade blood downstream of the installation (normal cycle), or to evacuate one or more tanks to the means of collecting rendering blood (in the event of an animal disease, found at the checkpoint), or again for washing, to evacuate cleaning fluids in the drain
  • the outlet for edible blood from the valve 17 is connected to a tank, called a buffer 19, which has sufficient capacity to continuously supply a centrifuge 20 located downstream thereof.
  • a tank called a buffer 19
  • the capacity of the tank 19 can be of the order of 600 liters which in practice guarantees a continuous supply of the centrifuge.
  • the buffer tank 19 is connected at its outlet to two drainage circuits, one for the transfer of edible blood to the centrifuge, the other for the evacuation of the washing liquids to the sewer; these circuits are provided with liquid switching means.
  • a switching valve 21 and an isolation valve 22 are provided as above.
  • the centrifuge 20 of the conventional type is suitable for fractionating blood into cruor and plasma and delivers these bodies to storage means.
  • the latter include cruor and plasma buffer tanks 23 and 24 and final storage tanks 25, 26 and 27 of greater capacity, connected to the buffer tanks.
  • the quantities of plasma extracted from the blood being approximately twice as large as the quantities of cruor, two plasma tanks of 10,000 liters each can be provided for a single tank of cruor of the same capacity.
  • Diverter and isolation valves such as 28 and 29 are associated with the pipes to allow either to transfer the cruor or the plasma to the final storage tanks, or to perform a washing operation with discharge of liquids into the sewer.
  • the part of the installation intended for sheep is similar to that described above and is connected to the latter at the level of the storage means 23, 24, at the outlet of the centrifuges.
  • this part intended for large cattle does not include buffer tanks (such as 3.9) because of the lower rates of the chain for this type of animal (25 to 30 per hour): the primary tanks in number of 3 with a capacity of approximately 110 liters each (7 to 8 cattle) are sufficient to ensure a continuous supply of the centrifuge, while ensuring that the blood of an animal will not be transferred to it until the veterinary control of the animal will have been carried out (the passage time of a bovine between the entry counter and the exit counter is approximately 30 to 35 minutes).
  • the blood receiving chute 33 is slightly different for large cattle.
  • the bleeding corridor does not have positioning plates and the chute 33 comprises, on its upper face, two cheeks 33a and 33b located on either side of the collection slot 33c and inclined at opposite direction in inverted V, so as to guide the animal's neck on one side and the latter's legs on the other.
  • the beef is then positioned, as shown in Figure 4, arranged at 90 ° to the direction of advancement, the head passing on one side of the chute and the legs on the other.
  • the chute is provided, on the side of the cheek 33a called to guide the neck of the animal, with an external guide 34 adapted to spread the head of the animal.
  • the bleeding which is carried out for these animals at the base of the neck almost at the level of the chest thus delivers blood directly into the chute with negligible losses towards the outside and without risk of pollution.
  • the normal operating cycle of the installation consists in counting the animals in batches corresponding to the capacity of a primary tank and to direct, after the bleeding of the last animals of each batch, the flow of blood towards the primary tank which succeeds that which has just been filled by the previous batch; in the absence of intervention by the veterinarian on a cycle stop device (symbolized in 36 which is found if killed at the control post, the control unit controls the emptying to the food blood circuit of the tank containing the blood of the animals from the last batch checked.
  • visibly sick animals are preferably selected before slaughter to be the subject of a special procedure. This can significantly reduce the amount of blood sent to rendering.
  • the veterinarian can take the decision to empty only the tank which contains the blood of the sick animal towards rendering, considering then that the passage of this blood in the chute and the ducts did not contaminate these elements enough to make the blood of the following animals unsuitable.
  • washing cycles can be executed manually by delivering the various washing liquids into the installation, after having arranged the various circuits in the evacuation position towards the sewer.
  • automatic washing means essentially comprising: storage tanks for cold water, hot water, detergents and rinsing products, a distribution network for these liquids to the various elements of the installation and a control unit allowing the injection of said liquids and their rejection in the sewer according to a programmed cycle.
